In these two genera, the alleles that allow the synthesis of muscarine, have been completely lost, or silenced.

在这两个类属中，允许合成毒蕈碱等位基因已经完全丢失或静默。

Their work reveals that muscarine, another compound hallucinogenic to the mammalian brain, has been produced in the fruiting bodies of fungi for 60 million years.

他们研究发现另一种对哺乳动物大脑有致幻作用化合物——毒蕈碱，已经在真菌子实体中产生 6000 。

Many species within this family have conserved the alleles required to synthesizing muscarine until the present day, with a smaller subset of living genera within this family to lose this trait.

这个家族中许多物种直到现在都保留合成毒蕈碱所需等位基因，家族中只有一小部分活类属失去这种特性。
